In considering a Petition for a Writ of Mandamus, the Court finds that Petitioner has not established that he is indisputably entitled to a writ requiring the Nominal Respondent to order the Bureau of Corrections to fix his time sheet. Under the facts presented, determining the correct amount of time that Petitioner must remain incarcerated is not a ministerial act because the Nominal Respondent must review of four different Judgments and Commitments, one of which was imposed by the District Court of the Virgin Islands. Additionally, Petitioner has an alternate basis for relief because he can appeal a denial of his petition for a writ habeas corpus to this Court.
